IMPROVEMENT IN WHIFPLE-TREE PLATE,

flI-lp Stlgrtult taunt it in llgtfit amen patent ant mating part at thearm.

TO- ALL WHOM IT MAY CONCERN:

.- Be it known that I, JAMES B. CLARK, of Plantsville, inthe county ofHartford, State of Connecticut, have,

invented a new and improved Whifile-Tree Plate; and I do hereby declarethat the following is a full, clear, and exact description thereof,which will enable others skilledin the art to make and use the same,reference being bad to the accompanying drawings,' making a part of thisspecification, in which- Figure 1 is a front elevation of my inventionattached to the whifile-tree and cross-bar.

Figure 2 is a. section of the same. i Figure 3 shows the separate partsof my invention. :Similar letters oftreference indicate like parts. p Myinvention consists in .theuse or employment of three separate plates ofcast metnl, the first provided with a shaft in its centre, to which thesecond is fitted, and hcldin its'place by the third,

A designates the first plate, B designates the shaft, and C the tenon onthe end' of "the-shaft B.

The second plate, D, has a'bearing,-E, made to fit the shaft 13, alsoallarg er bearing, F, made to fit the edge of 'the third plate, G, whilethe centre of .the third pla'tdG fits the tenon G. 1 p

The first and second plates A and D are provided with arms 7 h 7:, inwhich are screw-holes, for fastening the plates to the cross-bar K andwhiffle-tree L. One arm, it, on oacl1 p'lat e is turned or set atmightangle with the plates, in order that two screws can be placed in thebottom of the whifile-tree L, and two in the top of the cross-bar K, andone on the side of each, which secures the plates firmly in theirplaces.

The shaft 13, tenon C, bearings E and F, and the third plate G, can beturned, milled, or finished in any proper manner.

When the parts are fitted, place the second plate D on the first plateA, with the shaft B in-the hearing E.

Next, place the third plate G in the bearing F, with the tenon C throughits centre, and secure it in its place by rivets through the holes z. ri

'If desired, the tenon C and the centre of the third plate Gr might bethreaded, 'and thus hold in its place the third plate G.

The tenon C might be made long enough to upset, and thus hold the'thirdplate-G in its place. T, in fig. 2, designates a hole, which is filledby the whiflie-itree bolt M in 1.

NN designate the rivets that hold the third plate G in its place Theplates-thus held together "make an easy-working joint, and one perfectlysecure of itself, without the aid of the whifile-tr'ee-holt 7 By myinvention I produce a whiflile-tree plate with a large bearing,- holdingthe whifile-tree firm in its place, and not liable to rattle. If neatlyfitted, dirt or sand cannot get into the bearings, causing them to wearout Should the Whittle-tree bolt M, accidentally or otherwise, heremoved, the plate will hold the whiflle-tree in its place, andconsequently is a safeguard against accidents. v

What I claim as new, and desire to secure by Letters Patent, is-- Awhiflle-tree plate, with its shaft 13, tenon C, bearings E and F, andthird plate G, all constructed. and

' Operating substantially as described,

. JAMES ,B. CLARK.
